Patent number: 5509162Abstract: A cylindrical brush of the type utilized in an industrial type sweeper is retained on one end by an idler broom arm. The idler broom arm is hingedly connected to a member transverse to the brush such that the broom arm swings outwardly from the brush to effect a brush change as the broom arm is pivotally retained. A latch retains the arm in its closed position. The hinge is located radially behind and axially outwardly relative to the brush. This offset location of the hinge creates an inward biasing of the broom arm during forward travel of the sweeper to retain the brush between the idler broom arm and the driven broom arm on the opposite side of the brush.Type: GrantFiled: November 22, 1994Date of Patent: April 23, 1996Assignee: Clarke Industries, Inc.Inventor: Jack L.
